The Rouge measures 1.5 miles (2.4 km) wide by 1 mile (1.6 km) long, including 93 buildings with nearly 16 million square feet (1.5 km²) of factory floor space. With its own docks in the dredged Rouge River, 100 miles (160 km) of interior railroad track, its own electricity plant, and ore processing, the titanic Rouge facility was able to turn raw materials into running vehicles within this single complex, a prime example of vertical-integration production. Over 100,000 workers were employed there in the 1930s.
